Abstract
Disclosed herein are zeolite compositions comprising structural units of the formulae: wherein 'B' and 'C' are spacer groups comprising Cto Chydrocarbyl groups; and Rand Rindependently of each other comprise alkali metal, hydrogen, or Cto Calkyl groups. The zeolite compositions further comprise structural units derived from a heteropolyacid compound of the formula: (M)(M)(M)O; where Mcomprises hydrogen or an alkali metal; Mcomprises phosphorus or silicon, and Mcomprises tungsten or molybdenum. Methods for preparing these zeolite compositions are also disclosed. The zeolite compositions are useful as catalysts for producing bisphenols.
